c# - How to access a dll with c#?

Question

I have this code in VB from an older application that uses a dll to search a database. Could you please tell me how can I do it in c#.

Pseek is the dll

Dim SeekForm As New PSeek.cSeek
            Dim redRow As mscomctl.ListItem
            Dim succ As Long
            Try
                redRow = Nothing
                succ = SeekForm.CallSeekForm(My.Settings.PSeekConnectionString, "SELECT id,naziv,adresa,broj,vlez,stan,mesto from vSifrarnik where Firmaid = " & My.Settings.curFirma & " and Siftipid=" & SifTipIDUltraCombo.Value, "id,naziv,adresa,broj,vlez,stan,mesto", redRow, 1, , True, False)
                If Not (redRow) Is Nothing Then
                    SifraIDUltraTextEditor.Text = redRow.Text
                    SifraIDUltraTextEditor.Focus()
                End If
            Catch ex As System.Exception
                System.Windows.Forms.MessageBox.Show(ex.Message)
            End Try

添加 dll 文件，右键单击您的项目，然后添加引用并选择 dll 文件。然后在您的代码类型中
